It won't be until autonomous driving starts to drastically reduce the population that owns cars before you see significant decline in road use.
Autonomous vehicles that aren't owned by individual drivers (or rather, passengers) would increase road use. With the current situation, a driver drives from origin to destination and the car stays at the destination until the driver returns. With automation, the vehicle drives from origin to destination and then continues to the next trip origin. Unless, for every trip from point A to B, there's always somebody already at point B that wants to go to point C (as opposed to somebody at point C that wants to go to point D), the autonomous, no-passengers drive from B to C will be a net increase in road use.
What autonomous driving will really reduce is the need for parking.
